Abstract The demand for the exploration of highly active and durable electro/photocatalysts renewable energy conversion has experienced a significant surge in recent years. Metal‐organic frameworks (MOFs), by virtue their high porosity, large surface area, modifiable metal centers ligands, have gained tremendous attention demonstrated promising prospects electro/photocatalytic conversion. However, small pore sizes limited sites 3D bulk MOFs hinder wide applications. Developing 2D with tailored thickness aspect ratio emerged as an effective approach to meet these challenges, offering density exposed sites, better mechanical stability, assembly flexibility, shorter charge photoexcited state transfer distances compared MOFs. In this review, synthesis methods most up‐to‐date are first overviewed, highlighting respective advantages disadvantages. Subsequently, systematic analysis is conducted on identification electronic structure modulation catalytic applications conversion, including electrocatalysis photocatalysis (electro/photocatalysis). Lastly, current challenges future development toward efficient practical electro/photocatalysis proposed.

Abstract Covalent organic frameworks (COFs) with unique structural merits show substantial potential in the construction of biosensors. However, high‐performance COF‐based biosensors have rarely been reported due to special requirements for electrochemical biosensing.
